"Dear Fans, friends and supporters of Dark Funeral,
It is with great regret that we have to inform you today that our North American Tour has to be postponed. Due to circumstances and events way beyond our control, there is no other way but to postpone these dates. And yes, our triumphant return to the United States Of America is definitely not cancelled, but postponed. And we will try to announce the new North American tourdates as soon as possible, so you better stay tuned!
However, our appearance at the 70.000 Tons Of Metal-Cruise will take place as planned. Hope to see some of you there."
